A high frequency heating cooking apparatus is capable of preventing from rusting and reducing the cost substantially at the same time. The heating compartment of the high frequency heating cooking apparatus of the invention comprises a side wall, a top panel, and a bottom panel. By folding and plating one plated steel plate, the side wall having a left side wall, a right side wall, and a back side wall is formed. The plated steel plate has a function of preventing from rusting. The top panel is made of a stainless steel material, and this top panel has a power feed port, an intake hole, and an exhaust hole. The side wall made from a plated steel plate does not have opening ends of holes such as intake hole and exhaust hole.

High frequency heating cooking apparatus and manufacturing method thereof

A pressure cooker with a humidity sensor or gas sensor, wherein a micro-computer reliably detects the point at which the internal pressure of a pressure cavity reaches a prescribed value by using this sensor by detecting the point at which a pressure control valve begins to operate and begins to discharge a large quantity of excess vapor or gas etc. from the pressure cavity to the outside, with a result which is equivalent to that of a direct measurement of the internal pressure with a pressure sensor, thereby attaining an accurate measurement without bringing the humidity or gas sensor into contact with the pressure cavity.
